Description
ATtiny417/814/816/817
tinyAVR® 1-series
Introduction
The ATtiny417/814/816/817 are members of the tinyAVR®1-series of microcontrollers, using the AVR® processor with hardware multiplier, running at up to 20 MHz, with 4/8 KB Flash, 256/512 bytes of SRAM, and 128 bytes of EEPROM in a 14-, 20- and 24-pin package.
The tinyAVR®1-series uses the latest technologies with a flexible, low-power architecture, including Event System, accurate analog features, and Core Independent Peripherals (CIPs).
Capacitive touch interfaces with Driven Shield+ and Boost Mode technologies are supported with the integrated Peripheral Touch Controller (PTC).
Attention: Automotive products are documented in separate data sheets.
